Adapted from a book written by Marlene King, Pretty Little Liars is an American teen drama mystery/thriller television series set in Rosewood, Pennsylvania, following the lives of Aria Montgomery (Lucy Hale), Spencer Hastings (Troian Bellisario), Hanna Marin (Ashley Benson) and Emily Fields (Shay Mitchell), whose lives are being haunted by a mysterious "A."

My interest for Pretty Little Liars grew in the beginning of season 2, because I felt the storyline of the show really began to evolve. I am really into those movies with suspense, though I am not too gutsy, with horror movies, thus PLL were the ideal series for me. Thus, if you need a dramatic thriller to keep you on the edge of the seat, PLL is my recommendation.

After the disappearance of Alison DiLaurentis (Sasha Pieterse), the quintet of friends fell apart. Only reuniting one year later after the body of Alison was found. This series of unfortunate events bombard the girls one after another, as they encounter a mysterious figure by the name of "A" who presumably stalks the girls, threatening to unveil their deepest and darkest secrets; secrets that only Alison knew.

Returning with its second season, the first season that premiered on January 3rd 2011 kicked off with the girls reuniting to attend Alison's funeral. This comes followed up by the girls continually receiving text messages from 'A' who commands them to do certain things - otherwise face the consequences of having their secrets exposed. Initially, the girls thought 'A' was Alison, however, this became impossible because of her death, so the secret remains, who is 'A'?

Season 2 concentrates on the development of 'A' and her power to manipulate the girls. A brief summary of the episodes that have already aired are as follows:
